LOOSE-LEAF BOOK.

Application filed March 4, 1927. Serial No. 172,622.

This invention relates to a new and improved loose leaf book.

The main object of the inventlon is the production of an improved loose leaf book,

the parts of which are so shaped, connected and arranged as to permit a more ready, easy and efiicient operation of the book in use and in the removal and insertion of leaves, and in which the book is more effectively maintained from distortion and changes in shape and form, and whereby a more permanent and lasting. structure is provided 1n which the covers are freely movable with respect to the housings which carry the leaf. supporting posts. .i

Other objects and advantages relateto the details of the structure and the form and relation of the parts thereof, all as will more fully appear from. the following descript on taken in connection with the accompanying drawings, in which:

Figure 1 is a perspective view of a portlon of a loose leaf book ofthis inventlon illustrating the posts separated from one of the housings, but connected with the other.

Figure 2 is a perspective view of the same book showing the posts secured to both housm s.

Figure 3 is a lateral cross-section through the book.

Figure 4 is a similar sectlon showing the book opened.

Figure 5 is a section on line 55 Figure 3. Figure 6 is a plain view of the sl1de. Figures 7, 8 and 9 are perspectlve views of different forms of posts;

The loose leaf book as here illustrated comprises two covers 1-- and 2 which may be faced by a binding strip 3 of leather,

4 canvas or the like, and which extends over all or a portion of the surface of the covers and around the rear of the book. In addition a second binding strip 4 1s provided which may be bound into the covers 1- and 2, the latter being formed of cardboard or the like, and this strip 4- also extends around the rear end of the book. and may be separated from the strip '3 at the rear end of the book by means of a binder board 5-.

The covers 1 and 2 may be formed.

of layers of cardboard or the like secured together between which layers the ends of the strips 4-- are secured. In addition each of the covers -1- and -2 carries a plate 8 preferably of metal or the like which extends rearwardly from the covers when the latter are in closed position. Preferably these plates each comprise two thicknesses of sheet metal and each is formed from a single strip of sheet metal return bent upon itself and provided with an end portion extending at an angle to the body of the strip and A back plate 11 is provided preferably the rear ends of leaves secured in the book are adapted to contact. At its opposite edges the back plate 11- is formed with spaced barrels -12 mounted upon the pivot rods For the purpose of removably carrying the leaf supporting posts there are provided two housings -11- and 15 in the form of rectangular tubes and having at their rear ends spaced barrels 16 and ,'17 respectively mounted upon the pivot rods 7." It will be apparent that the plates 8 formed of a flat sheet of metal and with which with their respective covers -1 and -2,

the back-plate --11- and the housings 14- and -15 are all pivotally supported with respect to each other upon the pivot rods 7. Each housing is formed with a plurality of transverse aligned openings in its opposite walls for the reception of the posts l3-. In this illustration five posts are shown, and each of the housings is formed with five sets of aligned openings. The inner openings 27 in the housings when the book is closed are ofan area approximately.

the size of the posts, --13 and of substantially the same' shape, while the outer openings 22- are smaller and are tapered to receive the tapered ends --18 of the posts,

and for the purpose of holding the posts rigidly in position with respect to the housings there are provided similarly shaped slides -l9- of a width substantially the same as the interior width of the housings, but of a thickness substantially less than the thickness ofthe housings, as for instance substantially half the thickness, and these slides are formed with pintles 20 raised from one surface and adapted to move through openings 21- inthe opposite ends of the posts. The complete thickness of the slides -l9- and raised pintles -20 is substantially equal to the interior width of the housings -14 and 15-- and the reduced ends of the posts 13 are held tightly inthe comparatively -small tapered openings in the outer sides of the housings. f 7 It will be apparent that the plates 8 are in effect portions of the two covers respectively in that the plates are rigid extensions of the covers and move wlth the covers,

- and for the purpose of the claims of this application, these plates may be deemed portions of the covers for effecting a pivotal con nection of the cover to the back plate and to the tubular housing.

Each of the slides 19 is preferably pr0- vided with a hook portion 60 adapted to" form a grip for moving the slides.

The posts -13- may be of various forms so long as they are provided with tapered ends 18, and in Figure 7 a post of generally rectangular cross-section is shown, while in Figure 8 a post generally square in crosssection is shown, and in Figure 9 a post gen- .erally circular in cross-section is shown.

For the purpose of receiving the tapered ends 18 of the posts, the plates 8 are provided with openings 61 aligned with the endsiof the posts when the latter are inserted in the housings, and of a sizeadapted I to substantially fit the ends of the posts.

Altho I have illustrated and described a specific structure as constituting a perhaps preferred embodiment of this invention, I do not desire to restrictmyself to the details of the structure or the particular form and relation of the parts thereof, as various changes and modifications may be made within the scope of the appended claims.
